We replaced our washing machine and have discovered that when it starts to pump out the tub that the water comes out so fast that it overflows the drain pipe causing perhaps as much as several pints of water to spill on the floor.

The machine is located in a very small area off the kitchen and there is no room for a laundry sink.

Does anyone make some sort of overflow tank that could be mounted under the house? Or is there perhaps some other method to correct this problem?

Both the wall behind the machine and some of the sub floor will have to be replaced because of the water damage that has occured so far.
